False; Valence electrons are important for determining an atom’s chemical properties.
The correct statement is: Valence electrons are important for determining an atom’s chemical properties.
To understand this, let's first define valence electrons. Valence electrons are the electrons located in the outermost energy level (also known as the valence shell) of an atom. These are the electrons involved in chemical reactions and interactions with other atoms.
Valence electrons play a crucial role in determining an atom's chemical properties because they are responsible for bonding between atoms. The number of valence electrons an atom has determines its ability to form chemical bonds and the types of bonds it can form. Atoms with a full valence shell (generally eight electrons) are stable and tend not to react with other atoms, while atoms with partially filled valence shells are more likely to form bonds in order to achieve a more stable electron configuration.
Furthermore, the number of valence electrons also affects an atom's reactivity. Atoms that have one or a few valence electrons tend to be more reactive and readily form bonds to complete their valence shell. On the other hand, atoms with a full valence shell are generally inert and less likely to participate in chemical reactions.
So, in summary, valence electrons are crucial in determining an atom's chemical properties, such as its ability to form bonds, the types of bonds it can form, and its reactivity.
